Title:
SIMULATION METHOD FOR SHEAR FRACTURE OF DEFORMABLE OBJECT AND MATERIAL SIMULATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/116456
Kind Code:
A1
Abstract:
The present invention relates to a simulation method for shear fracture of a deformable object, which facilitates medical applications such as virtual operation training and interactive operation planning. A composite finite element model is used to simulate the shape of a deformable object, and when and how to generate new cutting are determined on the basis of Griffith energy minimization, so as to realize interactive virtual cutting simulation. Furthermore, a material simulation method is designed to ensure that the indentation is consistent with a cutter blade and the indentation induces deformation visually, so that a large amount of calculation is avoided.
